digitalmars.D.bugs - doc error: expression.html NAN !=

"Equality for floating point types is more complicated. -0 and +0
compare as equal. If either or both operands are NAN, then both the ==
and != comparisons return false. Otherwise, the bit patterns are
compared for equality."
The second line should read:
If either or both operands are NAN, then == will return false and !=
will return true.
